a424f92b55 Make MemTraceDriver no longer be UnitTestModule 
This makes it trickier to hook the driver up to sbus since we need to
assert its io.start.  We still need io.finished coming out of it to tell
when the trace finished.

e40b7f0b8b Support receiving trace filename from VPI for loggers 
Useful for testing with different memtraces without having to recompile
design.  This worked before for the trace driver but not for trace
logger.

Usage: make CONFIG=MemtraceCoreConfig run-binary-debug BINARY=none \
       EXTRA_SIM_FLAGS="+memtracefile=nvbit.vecadd.n100000.filter_sm0.lane4.broken.trace"

af01e39b5a Revamp dataflow between uncoalescer and inflight table 
Now uncoalescer no longer handles constructing and enqueueing entries
to the inflight table; it simply queries the table and works with the
found row.  Enqueueing / looking-up of the table is clearly split
between request and response flow.

6660775956 Synchronize requests across lanes from MemTraceDriver 
Otherwise memtrace driver might send single-warp requests split into
multiple cycles, and coalescer (CoalShiftQueue) thinks they belong to
different warps.

e02e4ca500 Handle backpressure from CoalescerNode 
Now do proper sourcegen for the tlCoal edge that's coming out
of the coalescer manager node.  This also prevents inflight table from
being full.

This means we move setting source ID of coalReq to outside the
coalescer, because sourceGen needs looking into response bits as well,
which is easier to do outside coalescer at the toplevel.

FIXME: coalescer unit test is still broken.
